A straddle type monorail is the most widely used as means urban transportation system. It can be implemented in order to solve the problem of urban transportation and to support the concept of a light transit urban mobility of sustainable transport system. In the last five years, PT. MBW has started a study the design and manufacturing of straddle type monorail in Indonesia. In this research, we intend to propose the new design concept of the bogie more specific than the design standard available because the urban city topography in Indonesia has not developed yet to provide an area specific for installation a monorail facility. One of the design parameters that will be improved is the turning-ability and gradient-ability. The normal standard turning ability of a monorail for some products in the world has a minimum radius of 40-60 m, while the gradient-ability is about 5-6%. The preliminary analysis in this research is to improve the turning abilities of monorail bogie and the effect of monorail motion stability. Bogie design will be accomplished by using the method of virtual prototyping.
